Chapter 377 Magnetized Target Fusion

"Academician Peng injects argon gas and liquid sodium into the hole, allowing the liquid sodium to absorb the heat generated by fusion, and then uses it to boil water to generate electricity. By exploding several hydrogen bombs every day, he can use this heat to generate a large amount of electricity."

"Don't think it's outrageous. In fact, with our engineering capabilities and technology, this plan is completely achievable in theory. However, this plan is still too simple and crude."

"Although it does not need to consume a lot of energy to maintain nuclear fusion, the energy conversion efficiency is relatively low and a large amount of nuclear fuel will be wasted. Unless other routes for controllable nuclear fusion are blocked and the energy problem is very severe, otherwise The probability is that this option will not be adopted.”

"However, scientists around the world have also been optimizing the inertial confinement scheme of nuclear explosion fusion power plants by continuing to shrink the reaction device, laser ignition and other methods."

"Nowadays, there are many solutions for inertial restraint devices, and the structures are all kinds of strange, but its essential engineering structure principle is very familiar to everyone, and that is the internal combustion engine in a car!"

"It's just that it uses a different kind of fuel. Compared with an internal combustion engine, it requires extremely high energy density and precise symmetry to achieve compression. Engineering, materials and other technical difficulties are very difficult."

After introducing inertial constraints, Kang Chi released another picture.

"After understanding inertial confinement and magnetic confinement, it should be easy for everyone to understand magnetized target fusion. This fusion device that combines magnetic confinement and inertial confinement was first proposed by scientists from the Maple Leaf Country. The one in the picture is a universal Fusion Corporation’s original magnetized target fusion prototype.”

"It is actually a circle of steam hammers added to the outside of the spherical tokamak device. The steam hammer pushes the liquid metal inside the sphere and pressurizes the deuterium and tritium plasma in the device to achieve the conditions for the fusion reaction."

The girl smiled sheepishly.

"In order to solve this problem, General Fusion designed a second-generation device, replacing the spherical tokamak with a cylindrical shape, allowing it to rotate to generate centrifugal force, so that the liquid metal evenly covers the four walls."

"At the same time, the fusion reaction will also produce neutrons, which can react with lithium in the liquid metal to generate more tritium, thereby achieving the purpose of continuing the fusion reaction."

"The biggest problem is that liquid metal is difficult to control. It is like water in the device. It is difficult to spread it evenly and compress the plasma."

"it's actually really easy."

"Then do you think it is possible for them to become the first country to commercialize controllable nuclear fusion? If we want to catch up on this route, is it possible to catch up with them?"

"This design looks perfect, but there are actually many problems."

After hearing this question, Kang Chi couldn't help but nodded with satisfaction,
It seems that some students are still thinking while listening...

The girl who asked the question suddenly realized,
I just feel that the brains of scientists are really good...

"This is their second-generation device Lawson Machine-26. By controlling the program, they make the piston speed at the two poles faster and the piston in the middle slower, so that close to spherical compression can be achieved."

Upon hearing this, a female student immediately raised her hand and asked: "Don't this fusion ignition method concentrate the pressure on one point? If the cylinder is pressurized, won't it eventually become a pillar and share the pressure?"

"Not only does this allow the liquid metal to compress the plasma more uniformly, but the speed of the steam hammer is no longer so demanding, which can greatly improve the energy efficiency of the entire device."

Kang Chi directly released the next picture.

Then she asked further: "Since Maple Leaf Country is currently in a leading position on the technical route of magnetized target fusion, are you optimistic about this route..."

This question sounds like a hype gimmick.
And asking this kind of question is basically a journalist’s professional instinct...

After hearing this, Kang Chi couldn't help but ask: "Are you a journalism student?"

No wonder,

"I'm sorry, I'm not a prophet." Kang Chi said in a tone without any emotion. "Scientific research itself also involves a bit of luck, so I can't give an accurate answer to this question."

“In fact, no matter what kind of plan it is, everyone may think it is perfect at the beginning of the design, but only through real experiments can we get the final answer. Generally speaking, experiments are full of surprises and challenges. of."

"The same is true for magnetized target fusion. It is a fusion device that has only emerged in recent years. I think it still has many theoretical and engineering technical problems that need to be solved." "Currently, General Fusion Company's second-generation machine is still under construction. If they The progress is going smoothly enough. If we follow the plan, we will achieve fusion ignition exceeding 1 million degrees Celsius by the end of this year, and reach scientific energy break-even next year, which is a Q value of 1.”

"Their ultimate goal is to consume 14 megajoules of energy per compressed plasma and produce an energy output of 704 megajoules, which is a Q value of 5.9."

"If they really succeed, it will barely meet the standards for preliminary commercialization... I can only say I wish them good luck."

Kang Chi then answered several students' questions, and the open class finally slowly came to an end.

After the video ended, Zhong Weijian was still holding his phone blankly.

After he pondered for several minutes, he sighed deeply and said: "The engineering difficulty of magnetized target fusion is definitely not as simple as 1+1, but..."

"This seems to be in line with the engineering miracles that Academician Kang has always created..."

Cheng Tao was stunned for a moment before tentatively asking: "So you agree with his point of view?"

"Does this matter?" Zhong Weijian returned the phone to Cheng Tao and stood up directly. "Now he is the chief engineer of China's controllable nuclear fusion. What he says is more important than any of us. Do you think this Is this open class for students?”

"Is not it?"

"Then you are underestimating him. He is obviously taking this opportunity to say hello to us in advance, and he is also telling the leaders."

After Zhong Weijian finished speaking, he turned around and entered the room, and then quickly walked out carrying a suitcase.

"Where are you going?"

"Dongyang."
-
At the same time, Kang Chi, who had finished his open class, had lunch with the leaders of Suzhou University and was on his way back to Dongyang in Yinhe.

Because he had been in public just now, Chen Hai didn't find a chance to talk to Kang Chi. Now that there were only two of them on Yinhe, he couldn't help but asked in a worried tone: "What did you say in the open class today?" If so...will it give rise to any ideas in Country M?"

"for example?"

"Increase investment in research and development of magnetized target fusion."

"Then let them add."

"Uh... so what you said today was actually to deceive them?"

"That's not true. Even if I want to deceive Lao Mei, there is no need to deceive me when I am giving lectures to students. Doesn't that disappoint everyone's desire for knowledge? So what I just said is the truth."

"As for whether Old M believes it or not, it depends on them..."

Kang Chi curled his lips indifferently,

"Even if they do choose to follow up, there's actually no need to worry at all."

"This thing is not as simple as building a fuel engine. General Fusion Company has made a demonstration animation of the LM-26 and published it, but who would think that they can build it by themselves just by watching the animation?"

"As for the fuel engine I just mentioned, the principle is actually the same. It is such a simple thing. There are a lot of drawings on the Internet, but in fact few companies can actually build engines well."

"Including us in the past, even if we reverse engineered the real thing, didn't it take a lot of effort from the boss to just come up with some knock-off products?"

"So you can rest assured, even if some things point the direction to them, they can only stare at it."
